Answer
Hi Ilana
I just saw your quesion in our answer pool.

I don't know how large your pond is, I have a smaller 90 or 100 gallon pond with goldies in it.  I clean mine out once a week, and same with my fish tanks inside.  Usually about 25% of the water is what I recommend unless the tank is overstocked, it's better to do it twice a week.  That helps keep the water parameters in check.
